Bug in .info file

The .info file when downloading the 2.8 tarball for D6:

; $Id: simpletest.info,v 1.4.2.2.2.4 2009/04/23 05:39:51 boombatower Exp $
name = "SimpleTest"
description = "Provides a framework for unit and functional testing."
package = Development
version = VERSION
core = 7.x
files[] = simpletest.module
files[] = simpletest.install

; Information added by drupal.org packaging script on 2009-04-23
version = "6.x-2.8"
core = "6.x"
project = "simpletest"
datestamp = "1240465894"

Note the "core = 7.x" at the top of the file. This is what prevents the module from installing when checked out from CVS.
